Chemical Structure

Methyl 4-(bis(trimethylsilyl)amino)but-2-ynoate CAS 112561-10-1 chemical structure

Description

The molecular framework of Methyl 4-(bis(trimethylsilyl)amino)but-2-ynoate (C11H23NO2Si2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Methyl 4-(bis(trimethylsilyl)amino)but-2-ynoate (CAS 112561-10-1), molecular formula C11H23NO2Si2 and molecular weight 257.48 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
